i think it would be very depressing to think of the fact that your child supposedly has another bro/sis but was aborted.
since it already taken place, i would think, its best to move on n not blame oneself.
it is a decision made by yourself, in whatever cirsumstances you were in, it probably was the best solution.
whether you wanna tell your dear husband anot, i think gotta see what kinda person your dear husband is.
can he take the news?
some guys can, they r understanding n wont probe.
but some guys would mind..
some say honesty is the best policy, but i think, if it will affect your relationship in a bad way, better not to.
